-LRB- CNN -RRB- Authorities in South Carolina have released dash cam video in connection with the fatal shooting of Walter Scott , but the footage does not show the actual shooting .

Video from the patrol car of North Charleston 's Michael Slager shows an initial traffic stop and early interactions between the officer and Scott .

Slager approaches Scott 's vehicle . The two men speak . Scott tells the officer he does not have insurance and is in the process of purchasing the vehicle . Slager then returns to his patrol car .

Scott exits his vehicle , briefly , and Slager tells him to stay in the car . Scott then gets out of the car , again , and runs away , out of the range of the dash cam .

The video , which was released Thursday , also shows a passenger in Scott 's car .

The passenger 's identity was not given in a police report obtained by CNN , but another officer responding to the incident said in the report that the passenger was detained and placed in the back seat of a police vehicle .

Scott family attorney Chris Stewart told CNN the man with Scott was a co-worker and friend . He did not identify the friend by name .

When asked what might have motivated Scott to run , Justin Bamberg , another attorney for the family , speculated that Scott might have been concerned about child support issues .

Scott owed back payments on child support totaling $ 18,104.43 , according to Charleston County family court documents obtained by CNN . He had a bench warrant issued against him for failure to pay at the time he was stopped by Slager .

But Bamberg was adamant the dash cam video does not alter what happened .

`` This dash cam footage does not change the fact that at the moment the officer shot and killed Mr. Scott -- that shooting was completely unjustified . And that is the key point of both the criminal investigation and the civil lawsuit , '' the lawyer said .

The North Charleston Police Department is not providing more information , citing an ongoing investigation of Scott 's killing that 's being conducted by the independent South Carolina Law Enforcement Division -LRB- SLED -RRB- .

Many questions remain about what happened on Saturday when Officer Slager pulled Scott over for what police have said was a broken taillight .

In the police report that CNN obtained , a responding officer said that Slager said that at one point he started to chase Scott down a street . `` Shots fired and the subject is down , '' the officer writes that Slager said . `` He took my Taser . ''

But a witness who shot cell phone video of the incident says he never saw Scott try to get Slager 's Taser .

Feidin Santana was walking to work when he saw Slager and Scott struggle on the ground , he told NBC 's Lester Holt on Wednesday . Santana then took out his phone and started recording video .

`` I remember the police -LRB- officer -RRB- had control of the situation . He had control of Scott , '' Santana said . Then , Santana said , he heard the sound of a Taser .

It seemed to Santana that Scott was trying to get away and avoid being zapped with the Tasered again .

On Thursday , a second witness spoke to CNN about what she saw . Gwen Nichols said she was in the neighborhood when she heard police cars speeding by and , curious , she followed them .

She saw Scott and Slager at the entrance to a vacant lot .

`` It was like a tussle type of thing , like , you know , like , ` What do you want ? ' or ` What did I do ? ' type of thing , '' said Nichols , who said she has not yet talked to police about what she saw .

`` I did n't hear Mr. Slager saying : ` Stop ! ' '' she said .

Feidin showed the video to the Scott family . But Santana has said fear for his own life almost kept him from revealing the tape .

In interviews with MSNBC and NBC , Santana recalled the moments when he recorded the video .

`` I ... thought about erasing the video , '' Santana told MSNBC 's `` All in With Chris Hayes '' in an interview that aired Wednesday evening . `` I felt that my life , with this information , might be in danger . ''

The video shows Slager shooting eight times at Scott as Scott runs away .

Witness : I nearly erased shooting video out of fear

An autopsy showed that Scott suffered multiple gunshot wounds to the back of his body .

Before the officer starts firing his gun in the video , a dark object falls behind him and hits the ground . It 's not clear whether that is the Taser .

Later in the video , when the officer approaches Scott 's body , he drops a dark object next to the man . It 's also not clear whether that is the Taser .

It 's unknown whether Scott took the officer 's Taser or whether the officer picked the object up and moved it closer to the body .

Slager has been fired and charged with murder . He is white . Scott , who was unarmed , was black .

Timeline of events

Scott 's shooting stirred memories of the Michael Brown case in Ferguson , Missouri , where an unarmed black teenager was killed by a white police officer . A grand jury declined to indict the officer in that case . But not everyone agreed that Scott 's case is like Brown 's or that race was a factor .

Asked how he felt about Slager being charged with murder , Santana answered that `` no one can feel happy . ''

`` He has his family , and Mr. Scott also has his family , '' he told Holt . `` But I think , you know , he made a bad decision . ... Mr. Scott did n't deserve this . And there were other ways that can be used to get him arrested . And that was n't the proper way to do that . ''

Lessons learned from Ferguson to North Charleston

The FBI is investigating , as is SLED .

`` I have watched the video , and I was sickened by what I saw , '' North Charleston police Chief Eddie Driggers told reporters Wednesday .

Mayor Keith Summey spoke at the same news conference , which was repeatedly interrupted by protesters who chanted : `` No justice ! No peace ! '' They called for the mayor to step down .

Summey said that the city has ordered an additional 150 body cameras `` so every officer on the street '' in the city will have one . That is in addition to 101 body cameras already ordered , he said .

Just before the conference was set to begin , demonstrators walked in . They were led by a man wearing a `` Black Lives Matter '' T-shirt who shouted , `` This is what democracy looks like ! ''

2010 census data show that North Charleston is 47 % black and 42 % white . The makeup of the city 's Police Department is unclear , though it 's been widely reported that 2007 federal figures indicated it was about 80 % black . Three of 10 City Council members are black .

It 's unclear what Slager 's motivation was , or if race played a part in Scott 's slaying .

`` We ca n't get into the brain of another individual , so we ca n't state that , '' Scott family attorney Stewart said . `` I think it would be irresponsible to say that and try and inflame a community or anything of that nature . ''

If convicted , Slager could face life in prison or the death penalty .

Who is Officer Slager ?

An autopsy of Scott showed that he `` sustained multiple gunshot wounds to the back of his body , '' and his death was the result of a homicide , the Charleston County Coroner 's Office said .

Asked whether CPR was performed on Scott after Slager shot him , Driggers said : `` In the end of it -LRB- the video -RRB- , what I saw was -LRB- what I -RRB- believed to be a police officer removing the shirt of the individual and performing some type of life-saving -LRB- procedure -RRB- , but I 'm not sure what took place there . ''

When Scott 's brother Anthony saw the video , he was convinced Slager 's account of what happened was not true , he told CNN .

`` There was not a struggle for the Taser , '' Anthony Scott said . `` I did n't believe my brother would have done that anyway . ''

To Anthony Scott , the videotape shows his brother was `` running for his life '' away from the officer .

`` I think my brother was thinking he was not going to be shot , no one would have thought that , '' Scott said .

Family members have adamantly repeated that they do n't want protests over Scott 's slaying to become violent .

And , so far , the demonstrations have been passionate but peaceful .

Scott 's mother , Judy Scott , told CNN 's Anderson Cooper that she feels `` forgiveness in my heart , even for the guy that shot and killed my son . ''

`` He was a loving son , a loving father , '' she said . `` He cared about his family and ... no matter what happens , it will not replace my son . ''
